Last updated: April 19, 2026
This Privacy Policy describes how the developer ("we", "us", or "our") handles user information in the mobile application "DokoOita" (the "App").
1. Information We Handle
The App handles the following information only on the user's device.
[Information entered by the user]- Photos (taken with camera or selected from gallery)- Text entered via voice input- Text entered manually- Numerical data such as dates, prices, and quantities
[Information handled automatically]- Device storage (for saving photos and data)- Information related to advertisement delivery (see "5. Advertising" below)
2. Where Information Is Stored
All data entered by the user (photos, text, budget information, legacy notes, etc.) is stored only on the user's device.
No data is ever transmitted to or stored on our servers.
When data is saved to external storage (such as the Download/DokoOita folder) via the backup or export function, the destination is limited to the user's device or a location specified by the user.
3. Device Permissions Used
The App uses the following permissions to provide its features:
- Camera: for taking photos- Storage (photos and media): for saving and loading photos- Microphone: for voice input- Internet: for advertisement delivery and AI analysis features
4. About the AI Analysis Feature (Receipt Reading)
When the user explicitly selects "AI analysis" in the "Bulk register from receipts" feature, the captured receipt image is transmitted to an external AI service provider's server, which automatically reads the store name, item names, and prices.
- AI analysis runs only when the user explicitly selects it- If "manual entry" is selected, images are not transmitted externally- Transmitted data is handled according to the AI service provider's privacy policy- We do not retain the transmitted image data
5. Advertising
The App uses Google AdMob, an advertisement delivery service provided by Google.
AdMob may collect the following information for advertisement delivery:
- Advertising identifier (Android Advertising ID)- Device type and OS version- Approximate location (based on IP address)- App usage information
This information is not used to personally identify users; it is used to display more relevant advertisements.
For details on advertisement delivery and how to opt out, please refer to Google's Privacy Policy.
Google Privacy Policy:https://policies.google.com/privacy
To disable ad personalization:Go to your device "Settings" → "Google" → "Ads".
6. About Voice Input
The voice input feature uses the OS-standard speech recognition on the user's device (such as Google Speech Recognition).
Voice data is handled according to the privacy policy of the respective OS provider (Google, device manufacturers, etc.).
7. Data Export and Sharing
The App provides features that allow users to export or share their data externally:
- CSV / PDF export- ZIP export (including images)- Sharing via messaging apps, email, etc.
These actions are performed only when the user explicitly initiates them. How information is handled at the destination is the responsibility of the user and the respective service provider.
8. Disclosure to Third Parties
Except as required by law, we do not disclose user information to third parties.
However, as noted above, minimum necessary information is transmitted to the AI service provider (for AI analysis) and to Google (for advertisement delivery).
9. Children's Privacy
The App is not directed to any specific age group. We do not knowingly collect personal information from children under the age of 13.
10. Security
Because the App stores data locally on the device, the security of the device itself (screen lock, keeping the OS up to date, etc.) is most important. Users are responsible for appropriate device management.
11. Changes to This Policy
This policy may be updated as needed. Any changes will be published on this page.
